"Also (forbidden are) women already married, except those whom your right hands possess. Thus has Allah ordained for you. All others are lawful, provided you seek them from your property, desiring chastity, not fornication. So with those among them whom you have enjoyed, give them their required due, but if you agree mutually after the requirement (has been determined), there is no sin on you. Surely, Allah is Ever All-Knowing, All-Wise." - Quran 4:24 (read more)

But we would like to point out here that it has medical benefits to which attention should be paid, regardless of the difference of opinion among the scholars as to whether it is obligatory or mustahabb." - Islam Q&A
